To nZZw-bomit may] concern) I Be it known that I, FRANK A. BEASLEY, a citi en of the United States, residing at the county of Anderson and State of Kansas, have invented certain new and useful Improvements, inDe viccs for llcating Charges for Explosive-Engines. of wh ch the following" is a specification.

My invention relates to improvements in devices for heating charges for explosive engines. i

This invention is an improvement .upon the invention described in arrapplication filed by me l e ruary 21, 1911, having Serial Iimnber (309,875. I

Gnc' of the objects of my'present inven tion is to provide novelmeans for heating both the air which is employed for mixing with the fuel and the fuel mixture. I

A further object of my invention is to provide simple and flicicnt priming means by means otwhich' the engine may be readily started even in cold weather. I

Still another obiect of my invention is to provide novel and etiicient means for pre-. venting back-firing; g I I I Ty invention prov-ides also a novel construction of heating; chamber.

' Other features ot' novelty of my invention are hereinafter fully described and claimed. In the accompanying drawings, which illustrate the preferred embodiment of my invention. Figu e l'is a view partlyin elevation and partly in vertical section of my improved device Fig. 2 is an enlarged longitudinal vertical section'of a. portion of the air conductor, showing the valve in the position in which it closes the lateralinlet.

which communicates with the atmosphere and is normally closed by an outwardly opening check valve 11, which is held seated by a coil spring 12.

The other end of the fitting 9 is connected with an arm of a U other'arm of which is connected to one end of a horizontal pipe 14. the opposite end of which is connected with the fitting 7. which as provided with a longitudinal passage 15 thcrethrough, which connects with two lateral passages 16 and 17, communicating respectively with the interior of the pipe 14 and with the interior of a hori7ontal pipe 18, which is connected with the pipe 8.

A. butterfly valve 19 is provided in the passage 16.

An inwardly opening check valve 20 is provided in the pipe 18 and held normally seated bv a coil spring 21.

A similar check valve 22, also opening inwardly. is mounted in the fitting 9 between the outlet 10 and the carhureter end of the by-pass. A coil spring 23normally holds the valve 92 seated. p

The conductor 14 is provided with a tittin; 24 having a lateral opening, which is closed by aphng 25, in which is provided upper end of which is secured a filling cup 27 provided with a shut off valve 28.

In the U shaped portion 13 is placed porous filling" preferably comprising copper wire '29; The outer side of the vertical portion of the pipe 13 is provided with vertical radial fins or projections 30, which serve to carry the heat to the pipe 13. l ncircling the vertical portion of the pipe I 13 1s a chimney 31 having a closed bottom in which is fitted a burner 32, which may be of any desired type, and which is fed with fuel by a pipe 33 connected with a suitable supply tank, not shown.

Encircling the chimnev 31 is a casing 34, between which and the chimney 31, there is provided an annular space 35. to the upper part of which is connected an air inlet pipe, 3 which extends to the atmosphereth ough 37, with which the top of thechimney 31 is provided.

shaped pipe 13, the

The lower part of the casing 34 is connected to one end of'a pipe 38, the other end of which connects with the inlet of the carbureter. 2.

Thepipes 36 and 38 serve as an air conductor ed air to the carbureter.

The pipe 38 is provided with an inlet 39 which, when the heating device is in use, is normally closed by a swinging valve 40 When the heatingdevice is not in use,

for carrying heatthe valve 40 is'swung downwardly so as to open the inlet 39, upon which the carbureter will draw its air through said inlet.

lhe fitting 7 has mounted slidably in it a horizontal valve 41 having an opening vertically therethrough designated by 42. This opening is a passage 15, as shown in Fig. 3, when the valve is open. It is disposed in this position when the heating device is notin use.

When it is desired to use the heater. valve 41 is closed and the butterflv valve 19 is opened, as is the valve 28'. The burner 32 is also lighted. The gasolene will, flow throng?- the pipe 26 into the pirie 13 in which it will be heated. Upon the engine being cranked, the air will be drawn through the pipe 36, space 35, and pipe 38 into the carburetor, and thence past the valves 20 and 22 into the pipe 13. where it mixes with thegasolene vapor, and the mixture is then drawn through the conductor 14 into the fitting 7, above the valve 41, and from .thence, it passes into the explosion chambers 1. \Vhen the engine is started, the fuel will be drawn from the tank 4, through the pipe 3, the valve 5 being opened. It will pass by the path just described. after entering the carbureter 2, the air being obtained through the pipe 38 as just before described.

When the weather is warm. and it is not necessary to heat the air and fuel. the valve as is the valve 10. The mixbe taken directly into the-ex- 41 is opened, ture will then plosion chambers 1 throughthe, vertical passage 15.

In order that the condition of the flame of the burner 32 may be observed. a horizontal observation tube, 43, closed at its outer end by glass 44, is mounted. in the walls of the chimney 31 and the casing 34 opposite to the burner 32.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims,

may be made without departing from the spirit of my invention.

Having thus described my invention, what I-claim and desire to secure by Letters Patent, isz
